China email, Tel. +86 (29) 6499139, 6499400 ISO 9001 certified products:   mechanical seals - Xi'an Yonghua Group Co., Ltd. is specialized in welded metal bellows seals, pusher seals and high performance seals. Bellows Design Advantages: Xi'an Yonghua's bellows seals have no sliding secondary seals. This eliminates the problem of swale face "hang up. "the major cause of seal failure with spring-loaded seals. Effective contact of sealing faces is maintained, and leakage to the atmosphere is minimized. By using a static secondary seal, managing shaft or sleeve fretting and subsequent premature seal failure are avoided. Unlike springs, bellows are nonclogging and their durable design can withstand higher viscosity fluids and a higher concentration of solids. API-682 Qualified: The low-Temperature series seals meet and exceed the testing requirements as defined by API-682 specifications.
